Description

Technical Field

[0001] The present application relates to the technical field of denture processing, and particularly relates to a transfer unit before and after denture sintering. Background Art

[0002] Dentures are what people often call "false teeth". Just as "false legs" and "prosthetic limbs" are called "prostheses", the meaning of "dentures" is teeth that fulfill an "obligation" for humans. Medically, it is the general term for restorations made after partial or complete loss of upper and lower teeth.

[0003] Common denture blanks include zirconia blocks and zirconia discs. Removable connectors for facilitating robot clamping are detachably connected to the bodies of the zirconia blocks and zirconia discs. During the processing and production of denture blanks, after the denture blanks are processed by CNC, it is necessary to first transfer the processed denture blanks to an artificial operation table to separate the blank from the connector, and then transfer the blank after removing the connector to a drying oven to remove the moisture of the blank (the moisture of the blank is generated during CNC processing). Subsequently, the dried blank is transferred to a sintering furnace for sintering, and after sintering, it still needs to be transferred to a cooling rack for cooling.

[0004] However, before and after the above-mentioned denture sintering, there are often time differences in CNC processing time, the time for manually separating the blank from the connector, drying time, sintering time, etc. In actual production, the phenomenon of material stacking is likely to occur in a certain link, resulting in poor processing smoothness and low efficiency of the overall denture. Summary of the Utility Model

[0005] The purpose of the present application is to provide a transfer unit before and after denture sintering to solve the problems existing in the above-mentioned prior art.

[0006] To achieve the above purpose, the technical solution adopted by the present application is as follows:

[0007] A transfer unit before and after denture sintering includes: a transfer rack, a drying oven located below the transfer rack, a control cabinet connected to one side of the drying oven, and a linear slide table installed on the control cabinet;

[0008] The transfer rack includes a cylindrical shell with a hollow interior, a loading and unloading opening opened on the front side of the shell, a main shaft disc located at the bottom inside the shell, a rotating shaft coaxially installed on the main shaft disc, multiple groups of block material turntables and multiple groups of crucible turntables evenly spaced and sleeved on the rotating shaft, and a driving motor drivingly connected to the main shaft disc;

[0009] Among them, multiple groups of plastic fixtures are evenly spaced on the block material turntable, and multiple groups of zirconia block materials are inserted into the plastic fixtures through the first connectors. Multiple groups of crucibles are evenly spaced on the crucible turntable. The linear slide is used to transport the plastic fixtures, the crucibles, and the zirconia disk materials between the front end and the rear end of the linear slide. The front end of the linear slide corresponds to the position where an external robot grabs, and the rear end of the linear slide is close to the position of an external manual operation table.

[0010] In a possible implementation manner, the plastic fixture has a first socket for inserting the first connector.

[0011] In a possible implementation manner, the number of the block material turntable and the crucible turntable is at least two groups.

[0012] In a possible implementation manner, the drive motor, the drying oven, and the linear slide are all electrically connected to the control cabinet.

[0013] In a possible implementation manner, the zirconia block material is detachably connected to the first connector.

[0014] In a possible implementation manner, a second connector is detachably connected to the bottom of the zirconia disk material, and the zirconia disk material is inserted into the linear slide through the second connector.

[0015] In a possible implementation manner, the linear slide has a second socket for inserting the second connector.

[0016] The beneficial effects brought by the technical solution provided by this application at least include:

[0017] This application is provided with a transfer rack, a drying oven, a control cabinet, and a linear slide. There are multiple groups of block material turntables and multiple groups of crucible turntables in the transfer rack. Multiple groups of plastic fixtures are evenly spaced on the block material turntable, and multiple groups of zirconia block materials are inserted into the plastic fixtures through the first connectors. Multiple groups of crucibles are evenly spaced on the crucible turntable. The linear slide is used to transport the plastic fixtures, the crucibles, and the zirconia disk materials between the front end and the rear end of the linear slide. The front end of the linear slide corresponds to the position where an external robot grabs, and the rear end of the linear slide is close to the position of an external manual operation table. In this case, it is possible to adjust the time differences such as the CNC processing time, the time for manually separating the material block from the connector, the drying time, and the sintering time, improving the smoothness and processing efficiency of the overall denture processing.

[0031] In the embodiment of the present application, the linear slide is also called a linear slide or an electric slide, which is a transmission mechanism that converts rotary motion into linear motion. Its core working principle is based on a ball screw or synchronous belt transmission system to achieve high-precision and high-efficiency linear motion.

[0032] Figure 2 A schematic diagram of the structure of a transfer rack of a denture sintering front and rear transfer unit provided by an exemplary embodiment of the present application is shown, with its shell side wall hidden. The transfer rack 1 includes an internally hollow cylindrical shell 11, a material loading and unloading port 12 opened on the front side of the shell 11, a main shaft disk 13 located at the bottom of the shell 11, a rotating shaft 14 coaxially mounted on the main shaft disk 13, a plurality of groups of block material turntables 15 and a plurality of groups of crucible turntables 16 evenly spaced and sleeved on the rotating shaft 14, and a driving motor 17 transmission-connected to the main shaft disk 13.

[0033] In the embodiment of the present application, when the driving motor 17 is started, the spindle disk 13 will drive the rotating shaft 14 to rotate, and further drive the multiple block material turntables 15 and the multiple crucible turntables 16 to rotate. The external robot only needs to work at one station at the material placement and removal port 12 to complete the material placement and removal work.

[0034] Figure 3 A schematic diagram of the coordination of the plastic jig and the zirconia block of the transfer unit before and after denture sintering provided by an exemplary embodiment of the present application is shown, wherein a plurality of groups of plastic jigs 5 are evenly spaced apart on the block turntable 15, and a plurality of groups of zirconia blocks 6 are plugged into the plastic jigs 5 via a first connecting piece 61.

[0035] See also Figure 1 and Figure 2 A plurality of groups of crucibles 7 are evenly spaced on the crucible turntable 16; the linear slide 4 is used to transport the plastic jig 5, the crucible 7, and the zirconia disc material 8 between the front end and the rear end of the linear slide 4, the front end of the linear slide 4 corresponds to the position where the external robot grasps, and the rear end of the linear slide 4 is close to the position of the external manual operating table.

[0036] For further information, see Figure 3 The zirconia block 6 is detachably connected to the first connecting member 61, and the plastic jig 5 has a first plug hole for the first connecting member 61 to be plugged in. Figure 1, a second connecting member 81 is detachably connected to the bottom of the zirconia disk material 8, and the zirconia disk material 8 is inserted into the linear slide 4 through the second connecting member 81. The linear slide 4 has a second jack (not shown in the figure) for inserting the second connecting member 81.

[0037] Furthermore, the drive motor 17, the drying oven 2, and the linear slide 4 are all electrically connected to the control cabinet 3 to achieve the coordinated operation of each component. Optionally, the number of the block material turntable 15 and the crucible turntable 16 is at least two groups, and can be flexibly adjusted according to the actual working conditions.

[0038] It is worth noting that the above-mentioned detachable connection is a bolt connection or a bonding connection.

[0039] Next, in combination with Figures 1 to 3 the working principle of the intermediate transfer unit for dentures before and after sintering involved in the embodiments of the present application will be described.

[0040] Zirconia block material 6: After being processed by CNC, it is clamped and inserted by an external robot one by one onto the plastic fixture 5 placed on the block material turntable 15 in the transfer rack 1. After reaching the preset time, the external robot clamps the plastic fixture 5 filled with zirconia block materials 6 onto the linear slide 4, and clamps the empty crucible 7 on the crucible turntable 16 onto the linear slide 4; the linear slide 4 moves from the front end close to the external robot to the rear end close to the manual operation table, and the worker will remove the first connecting member 61 on the zirconia block material 6. Here, the zirconia block material 6 after removing the first connecting member 61 is defined as a semi-finished denture. The worker then puts the semi-finished denture into the crucible 7; the linear slide 4 moves from the rear end close to the manual operation table to the front end close to the external robot, and the external robot clamps the crucible 7 containing the semi-finished denture to the drying oven 2 to dry the water stains caused by CNC processing. The water stains will affect the sintering yield rate. Then the external robot clamps the dried semi-finished denture to perform sintering. After sintering, the external robot then clamps the sintered crucible 7 to the crucible turntable 16 for cooling. The crucible turntable 16 can be layered, and different crucible turntables 16 respectively place the empty crucible 7 before sintering and the crucible 7 that needs to be cooled after sintering.

[0041] Zirconia disk material 8: Since its CNC processing time is relatively long, it does not need to be transferred through the transfer rack 1. After the CNC processing is completed, the zirconia disk material 8 is directly clamped by an external robot onto the linear slide 4, and an empty crucible 7 is kept on the linear slide 4. If not, it is clamped from the crucible turntable 16; the linear slide 4 moves from the front end close to the external robot to the rear end close to the manual operation table. The worker will remove the second connector 81 on the zirconia disk material 8. Here, the zirconia disk material 8 after removing the second connector 81 is defined as a semi-finished denture. The worker then puts the semi-finished denture into the crucible 7; the linear slide 4 moves from the rear end close to the manual operation table to the front end close to the external robot. The external robot clamps the crucible 7 containing the semi-finished denture and goes to the drying oven 2 to dry the water stains caused by CNC processing. The water stains will affect the sintering yield. Then the external robot clamps the dried semi-finished denture and goes for sintering. After sintering is completed, the external robot clamps the sintered crucible 7 to the crucible turntable 16 for cooling. The crucible turntable 16 can be layered. Different crucible turntables 16 respectively place the empty crucibles 7 before sintering and the crucibles 7 that need to be cooled after sintering.

[0042] In the embodiments disclosed in the present application, terms such as "installation", "connection", "attachment", "fixation", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "attachment" can be a direct attachment or an indirect attachment through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments disclosed in the present invention can be understood according to specific circumstances.

[0043] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
